To all whom, t may concern: i

Be itA known that I, FRED L. BAILEY, "a citia new and'usefulImprovement'in Window- Shade Adjusters, of whichthe followingisaJ full,clear, and exactdescription, referencei being had to the accompanyingdrawings, which are made a partof this specification.

My invention? relates to improvements in the mechanism for lowering'orraising the roller which ordinarily carries the window# shade; and itconsists of features of novelty, which will be more fully and perfectlypointed out in they following description, in which Figure 1 shows thewindow-casing and the shade-adjuster in place with window-shadeattached, part of the shade being broken away to more fully show themechanism ofthe adjuster. Fig.` 2 shows a detail View of one end of theadjuster-frame. Fig. 3 shows an end view of the detail in Fig. 2. Fig. 4shows a detail guide-rail, the use of which Will be subsequentlyvpointed out. Fig. 5 is a detail cross-section on line 5 5 of Fig. 2.Fig. 6 shows a modification ot' the adjuster-frame. Fig. 7 is ahorizontal cross-section on line 7 7 of Fig. 6. Fig. 8 shows a secondmodication of the adjuster-frame. Fig. 9 is a cross-sectionon line 9 9of Fig. 8. Fig. 10 shows an alternative form for attaching the lowerroller of the adjuster-frame.

The window-casing 1 'has secured on either side a vertical guide-rail 2.This guide-rail is made of metal in the form of a small anglebar, as isclearly shown in cross-section, Fig. 5. A top view of rail 2 is shown inFig.' 4." These guide-rails 2 extend from the `top of the inside of thewindow-casing to the window-sill at the bottom. Between these rails isarranged a rigid carrier supporting at its upper end the shade-roll.This carrier,which will be called the adjuster, consists of a triangularframe 3, having small grooved rollers 4 at the upper and lower corners.These rollers 4 engage the guide-rail 2, and the two frames 3 areseparated and held rigidly apart by a rod 5. This rod 5 `passes througha collar G on eachof the triangular adj uster-frames and is held secureby a small set-screw orother means of clamping. The sleeve 6 is made sothat the rod 5 can pass serai No. 641,723. oro model.) v

through it, in 'this,my adjqsnngthe width `between`the nrollers 4 onthetwo sides of the window.' VA small angle-bracket,7` is secured to theupper partof each of theadjuster- -frames j`and extends out, as showninFig. 3, clear overthe frame 3. These brackets support the 'shaderoller8,on which the curtain 9 is rolled. These brackets 7 are madewith alongitudinal slot l0 in their base, so that theyv maybe adjusted to theexact length of the shade-roller 3.A The entire adjuster-:frame -is heldinfits'relative vertical position by the spring-catches 11, which engagesmall recessholes 12 in the guide-rail 2. These springcatchesf 11 arereleased by the cord 13, which passes through an opening in the rod 5and over a small pulley 14 at the top ofthe win- 1 7o j. The operationof this adjuster is as follows:

dow-casing.

APresuming the window-shade to be in the position indicated in Fig. 1,iirst it fis desired to raise the window-shade to the top of the window.The cord 13 is grasped and gently pulled. It first releasesthe catches,11 from the holes 12 in the guide-rail 2. Next, further tension put oncord 13 raisesthe adjusterframe vertically. The rollers 4 travel in theguide-rails 2. When the window-shade is high enough, the cord 13 isreleased. The adjuster-frame will then descend until the catches 11 meetthe first of the holes 12, into which they will enter, therebyarrestingthe downward course of the adjuster-frame. Of courseif Vthe catches 11happen to be opposite any of the holes 12 when the cord 13 is releasedthey will at once enter such holes 12. It it is desired to lower the topof the window'- shade, the cord 13 is rst tightened enough to releasethe catches 11. Then cord 13 is gently released, allowing the adjusterand windowshade to descend. The weight of the ad `juster-frame andwindow-shade being much greater than the strength of the small springswhich force the catches 11 into their respective openings 12, thecatches will remain dis` engaged so long as there is even a slighttension on cord 13; but so quick ascord 13 is entirely released thecatches `11 will at once engage in the nearest opening 12.

Vhen the window frames or casings are not of sufficient depth to placeangle-rails, as shown in Figs. 4 and 5, inside the casing,

IOO

then in order to make this invention available in such cases asmallraised rail 15, such will also be found a modified form of catch 11,operating by gravity instead of by spring.

In the rail 15 (shown in Fig. 6) will be found a modiiied form oforifice for the catch 11 to engage with, consisting of a smalltriangular notch 16. Window-case 1- originally for the use of this formof WindoW-shadeadjuster, a groovedY `rail 17, such as is shown in Fig.9, may be A mortised into the inside of the casing. In 4 this groovethesmall rollers 4, which iny this case need not be' grooved, Willtravel. The

Weight of the adj uster-t'rammand Window-- shade may be counterbalancedby Weight 18,

moving on the inside of the 'casing -1 inV a manner similar to thecounterweights for an ordi-- nary Window. Instead of catch 11 being usedfriction -springs 19 are intended to press against the bottom of thegroovedl rail-17,v forming sufficient resistance 'to maintain the framein any desired position, which can be .l

done by a cord secured tothe cross-bar 5,. f.

In this Way the Window` Where it is desired toplan the` passing over apulley`14, similar to the cord 13, and also a cord attached to 5 and'hanging directly down. (Not shown.)

Fig. 10 shows a modified form ofl securing the lower of the smallrollers 4 by a spring 20, the object of this being to allow for slightunevenness in the rail 2.

Having fully described my invention, the combination I claim is asfollows:

1.v In a Window-shade adjuster, the combination of a rod having bracketsat either end, the same being laterally adjustable, rollers mountedatthe upper and lower extremities of the brackets, 'guide-rails securedto the Window-frame for engaging the rollers anda catch for holding theframeat any desired position, and shade-roller brackets mountedv upon aframe for holding the shade-roller substantially asdescribed. i

- y2. The combination -ina Window-shade ad- -a -j ust'er of a rod 5,brackets-23; means for adjusting the brackets 3' laterally on the rod 5,

rollers 4 mounted a-t the upper andloWereX- tremities ofthebrackets,guide-rails 2 secured to the Window-frame, brackets 7 for fholding the shade-roller, the-roller y8 for hold# ing the shade andthecatches 11 for securing f the' -frameat any desired position, snbstan-4Jtially as described. l Y
